Oh my goodness we sure felt it. We love just north of Columbia in Blythewood, SC. First it sounded like the UPS truck barreling down the hill in our neighborhood at excessive speed, then the couch began shaking. Hubby and I stood up the floor was shaking. Totally bizarre event for sure. The dogs all started barking madly too. Yep three days of snow followed by an earthquake, hope someone is not trying to tell us something!!!!
